"Kids are very naïve at an age like that, it’s scary," said Angelo, who asked not to use his last name to protect his child's identity.

"You don’t want to scare your children, but you want them to be aware of situations like this," he said.

Wednesday night, the man approached the two children as they played outside a home on College Pond Road in Plymouth.

“I was pretty enraged," said Angelo. "The first thing I wanted to do is drive up there and find this person."

He said his daughter and her friend got a bad feeling about the man they’ve never seen before.

“You gotta take things like this serious," he said.

They say he walked right up to them, after pulling over in a red pickup truck, prompting the two girls to run inside.

“An older gentleman like that should not be talking to young girls like that, ever," he said.

When the mother of one of the girls rushed out to confront the man, she says he drove off into the community that’s surrounded by the Myles Standish State Forest.

“This is my only daughter. She’s my number one," the father said.

That's why he’s been scouring the area ever since, to make sure his daughter and other children are safe."I hope the police find you before I do," Angelo said, in a message to the man who approached the children.
